Well this is... a thing that happened.
Probably is as bad as the others but that never stopped me from doing this didn't? 
Chapter 1: Arrival.
One day in Koumakan, the mansion of the Scarlet Devil, Remilia became small and no one knew why.
Her best and closest friend Patchouli Knowledge told her she will do all she could to find the reason of her sudden shrinking. Though not a single bit of enthusiasm was found on her expression or voice at the moment, which even for someone as stoic as Patchouli, it was a little strange.
Days later Chibi Remi walked into the library to know what her friend may have found, “Patche, Patche!” she called on an adorable high pitched and squeaky voice.
“Welcome mistress,” greeted Patchouli’s devil assistant Koakuma with a gentle bow.
“Where’s Patche?” Remilia asked with curiosity, “I want to know what she has found so far.”
Koakuma seemed to be slightly startled by the question but smiled nonetheless, “Miss Patchouli is enjoying her tea at the moment,” she turned around, “I will lead you to her, mistress.”
Remilia liked that there was no big change in how the others treated her now that she was small. Obviously she got some d’awws and things like that, but no one treated her like she was some kind of baby and she was happy for that. Otherwise things wouldn’t have been so peaceful around here.
She gracefully followed Koakuma to her friend’s location. Well as gracefully as she could muster in her actual form, which was a bit hard considering how adorable she looked.
After navigating through the book ocean what was Voile Library, they arrived at a more open area where a table with two chairs was located. One of said chairs was occupied by Patchouli as she sipped from her teacup every now and then as she looked over a thick open book.
Koakuma stopped a few feet away, “Miss Patchouli,” she called courteously obtaining Patchouli’s attention, “Mistress Remilia wants to talk,” she stepped to the side after saying this.
Remilia flied to the other chair that was conveniently set out as if waiting for her to sit. “Patche, did you find anything yet?”
Patchouli slowly set her cup down and closed her book, then put her hands together and looked at her friend, “Remi, what happened to you is still a complete mystery to me.”
Remilia was not amused with the news, yet she controlled herself, “so, you haven’t found a thing?”
Patchouli slowly shook her head in negation, “the only thing I can say about this is that it’s not the same as what happened with Flan.”
“What do you mean?” Remilia said as she lifted a brow.
“For one, you can speak like you normally do. Even if your voice is somewhat higher in tone it is still your voice,” Patchouli pointed out, she let a few seconds to pass before continuing just to let her friend take it all in, “You also didn’t became childish, Flan’s behavior regressed to one of a toddler getting amused by simple activities. But that’s not the case with you Remi.”
Even though she was curious about how different her current situation was compared to her little sister’s. Remi still wasn’t happy with the results, “that still doesn’t help Patche!” she snapped while hitting the table.
Her friend kept calm and composed, wearing a stoic yet somewhat sympathetic stare, “Remi,” she started. “I have been looking for a solution non-stop for days, it weights on my conscience to say this but, maybe you should start thinking about how to cope with it.”
Remi’s left eye twitched involuntarily with a shocked expression and a gaping mouth. Enough to say… she was not happy about it.
Fast forwarding to present time, Remilia holding a new smaller parasol to protect herself of the annoyingly bright sun, found herself in front of the castle of friendship’s gates on Equestria.
She raised her free hand and knocked at the giant doors. Then she waited until someone attended her. She wasn’t happy to be there though, ‘I can’t believe I actually thought about coming here of all places.’
After a few moments Remilia was able to hear footsteps getting close to the door, as she listened she figured this may be that little dragon instead of a pony, “Coming!” She heard the young male voice from said drake as the door slowly opened, making annoying creaking sounds. Spike stepped outside shortly after, tried to block the sun hitting him in the eyes with a claw and looked at her for a moment.
“Oh? Hi Flan, I didn’t expect you around today, what’s the occasion?” Spike said out of sheer obliviousness.
Remilia looked at him with a raised brow, “excuse me?”
Spike was confused by the voice but when his sight got back to normal he noticed who was in front of him and flinched in surprise, “Miss Remilia!?” He gave a nervous bow, “s-sorry I mistook you with Flan, but w-what happened?” He asked.
Remilia could have retorted with indignation, but she knew better than lashing out at a kid. Not only that, but she knows that this drake did a lot for Flan, “Do not worry, Spike. As for what happened, even I don’t know how I ended up like this,” she emphasized while referring to her small self.
Spike feeling a little bit more reassured from Remilia’s response asked, “It’s the same that happened to Flan?”
Remilia shook her head, “no exactly, my friend Patche doesn’t believe is the same situation, I didn’t lost my ability to speak normally like Flan did, even though she can speak it is difficult for her, in my case it is not,” she waiting for Spike to process the information before continuing, “the only thing that is the same, is that our bodies shrunk to this size, other than that I’m still my normal self.”
“Ooooh,” Spike said in realization, but still had a question in his head, “if it’s not rude of me to ask Miss Remilia, what brings you here? Was a meeting scheduled or something?”
Remilia shook her head with a little smile on her face, “not at all Spike, since I don’t have too much to do until my friend finds a way to revert this situation, she suggested me to check this place out. Flan seemed to like it, so I figured, why not?” With that said, Remilia looked at the open castle doors, “is Sparkle inside, Spike?” She asked gently.
“Twilight? Yes, she’s here but she-“ Spike was about to continue but Remilia suddenly walked inside.
“Perfect, I’m sure she will be more than happy to receive me by surprise, right?” Remilia stated as she made her way in, closing her parasol and resting it on her right shoulder.
Spike stood outside looking at her go for a few moments as if his brain wasn’t able to catch up in time, before realizing it and rushing after her “Miss Remilia, wait!”
Remilia let the little drake catch up before asking, “What is it?”
Taking a few breaths, Spike started “I was trying to tell you, Twilight is in a reunion with Princess Celestia.”
Remilia raised a brow, “Who?”
“Eh?” Spike stared dumbfounded.
At that moment the lavender Alicorn made act of presence with a white alicorn in tow, “Spike? Who was there at-“ Twilight stopped as she made eye contact with little Remi and blinked a few times.
Remilia grinned amusingly at the silly face Twilight was making, but she was a lady and a lady must greet others accordingly, “Greetings Miss Sparkle, it has been a long time since our last meeting. Once again I thank you for continuously taking care of Flan for as long as she lives between the ponies,” she gave a little grateful head bow to the Princess of Friendship.
Twilight didn’t know what to think of this, but she had to say something at least, “M-miss Remilia!?” she said in surprised realization, “what happened to you?”
“I don’t know how, my friend is investigating as I’am here,” Remilia then focused on the other alicorn who politely waited in silence with a motherly smile, “I don’t think we have been introduced yet,” Remilia flew up to be at eye level, “I’am Remilia Scarlet, a pleasure to make your acquaintance,” She said as she tilted her upper body forward in a courteous bow.
The white alicorn replied with the same politeness the little vampire has showed her, “the pleasure is all mine, Miss Scarlet. I’am Princess Celestia monarch of the sun, I rule these lands of Equestria alongside my sister Princess Luna who unfortunately wasn’t able to be here with us today.”
Remilia had a small grin on her face, not menacing, not belittling, but somehow amusing, ‘this one seems interesting.’ She thought to herself.
“Excuse me, Miss Remilia,” Twilight called getting her attention, “I don’t intent to be rude, but what brings you here today? Are you looking for aid in your current situation?”
Remilia shook her head, “No, I’m here just to explore this world, I trust Patche with the research even if she has not made any notable progress yet.” With that said she looked at Celestia, “and your superior here picked up my interest.”
“What do you mean?” Twilight was confused.
Celestia just kept her motherly look, “Twilight, I think Miss Scarlet desires to visit Canterlot,” then focused on Remilia, “is my assumption correct?”
Remilia nodded, “it’s good to see we are on the same page Princess.”
“Why Canterlot though? Don’t you want to share some time with Flan here on Ponyville?” Twilight was confused as to why Remilia would not want to be with her little sister.
“Do not misunderstand Miss Sparkle, I will share time with Flan. I just don’t think Ponyville will be the most adequate place to be, for me in particular,” Remilia explained calmly.
“Why not?” Twilight wasn’t able to figure it out, Ponyville wasn’t that bad right?
“Let’s just say I have a feeling that something would really annoy me if I stay here,” Remilia replied, (As something pink could be seen bouncing in the distance from a window) then said to Celestia, “I do hope my desire to visit the city you rule is not out of place, Princess.”
“Worry not, Miss Scarlet. It would be an honor to have a guest of your caliber making us company in Canterlot’s Castle,” Celestia reassured with her smile always present.
Something still felt off to Twilight, but she didn’t want to become the thing that would annoy Remilia. So she let the situation go for the time being, that didn’t mean she wasn’t curious about what happened to Remilia, she would try to make some research herself to see what she can find.
Soon after the chariot that brought Princess Celestia to Ponyville had a new passenger on it. Besides some small talk, the trip was quite uneventful.
Remilia with her parasol open once again looked at the distance as they came closer to the more polished city, her long canines poked from the smile that grew on her face, ‘this will be fun.’
Chapter 3: Names and helping out.
Author's Note
Hey, everyone! 
Not deadge here 
K thx, enjoy 
Chapter 3: Names and helping out.
Celestia entered the dining hall and saw the other two already sitting, “you could have waited for me, you know?”
“I’m sorry sister, I just got too entertained on my conversation with Remilia,” Luna replied in defense.
“You shouldn’t apologize for something you had no fault at, Luna. It was her fault for staying frozen behind,” Remi remarked getting a look from Celestia at which she felt very satisfied.
Celestia let out a tired sigh before composing herself, “in any case, what are we having today for breakfast?” She asked Luna thinking she already ordered for them.
She did not expect her sister’s answer though, “Strangely enough, nopony came to receive our order yet.”
“Why am I not surprised?” Remilia said with a sigh herself, getting even more on Celestia’s nerves.
Luna felt bad due to the good impression she gave to Remilia was slowly worsening on her head, “Don’t worry Remilia, I’ll call somepony!” she said in a rush.
She was about to leave until Remilia held a hand up to signal her to stop.
“What is it?” Luna asked with a raised brow.
Remilia grew a cheeky smile, “Sakuya,” she called.
Before they could even blink both princesses saw a new being present standing just next to Remilia, it was a silver haired woman dressed in a blue French maid outfit.
She was just there standing with her eyes closed as if waiting for something.
Celestia opened her mouth to say something.
“Red tea and I’m in the mood for some millefeiulle,” Remilia spoke before Celestia could.
“And your guests, Mistress?” Sakuya said without changing her expression.
“What would you two like? Don’t be reserved, Sakuya will attend you to the best of her abilities,” Remilia surprinsingly adopted a more carefree and nice attitude.
Luna took Remilia’s word to heart and ordered something for herself, Celestia was hesitant though.
“Sister?” Luna asked with confusion as to why Celestia didn’t order anything.
Seeing the fidgety princess Remilia decided to ease the mood more, “Princess, I may not sympathize with how you do things and I really enjoy watching your reactions, but…” she softened her features, “I didn’t come here to cause mayhem or destruction, therefore no one under my orders will do anything of the sort either. I just want to have a nice time in the world my little sister enjoys being around so often,” she ended with a little smile which Sakuya and Luna mimicked.
“So, everything until now has been a prank?” Celestia asked with confusion.
Remilia using her left arm to support her head, mischievously looked at the solar princess, “Princess, I’am the Scarlet Devil, due to my noble heritage is blatantly obvious that I like to make fun of others from time to time,” she gave a playful wink in her direction.
Celestia deadpanned, but she finally was able to feel at ease with this clarification.
“That said…” Remilia adopted a more serious tone, “I still will not tolerate any kind of insubordination or mockery towards me regarding my current appearance, in the likely case of that occurring…” she spawned Gungnir in her index finger and balance it perfectly on it, “I will proceed to discipline whoever did it, is that clear?”
Luna gawked in awe at the bloody spear that Remilia just manifested.
While Celestia felt nervous again, “I understand your point Miss Scarlet, but could I please ask you to consult it with us before you do so? I’m unaware of what discipline exactly entails, so I’am just trying to be assured of my ponies’ wellbeing in case they commit such a mistake,” she tried to reason with the little vampire.
Dissipating Gungnir, Remilia thought about it while tapping her chin with a finger, she gave a small nod to herself, “Alright, Princess. I will humor you on this, after all I told you I just want a good, relaxing time for as long as I’m here. So if annoyances can be avoided, that’s much better.” Lazily resting against her chair she flashed a satisfying smile.
“Oh!” She suddenly said while jumping up, surprising the princesses.
“Is something the matter, Remilia?” Luna asked with some concern.
“It’s nothing bad, I was just about to ask if Sakuya can have access to your cooking installations?” Remilia gestured towards her maid, who was still patiently waiting.
They blinked a couple of times, “Oh, of course Remilia. She can use our installations as she seems fit,” Luna was the one to reply.
Celestia flared up her horn for a moment, “It is better if I call somepony to guide her there, then.”
“Very much appreciated you two,” Remilia gave a thankful nod and after Sakuya got Celestia’s order she swiftly left the dinner hall with the chef that was called to guide her.
“She’s a very stoic maid, isn’t she?” Luna curiously asked.
“I would say, she gives more of a professionalism aura, it looks like she takes her job very seriously,” Celestia pointed out.
Remi let out a giggle, “it’s interesting how everyone that meets Sakuya gets the same impression. She’s very strict with herself that much is true. But, she’s also very caring when you look past that cold exterior she likes to put up during duty time.”
“It reminds me to how Lucky Star was when she worked as a maid here in the castle. I would assume you two know each other, right Miss Scarlet?” Celestia asked.
“Lucky Star? Who is that?” confused, Remi asked while tilting her head to the side.
“That would be the pony name Konata took when she arrived in Equestria,” Luna clarified.
“Ooooh, that’s right. She lived here for a short while didn’t she?” Remi got a nod from both princesses in response, “Yes, we do know each other and if you got a similar impression from her when she worked as a maid, then she most likely took inspiration from Sakuya, I have no doubt about it.”
“Now since we have some time before breakfast. First of all…” Remi looked at Celestia, “Princess, is it alright if we drop formalities? I don’t think it’s necessary between us at this point.”
This took Celestia by surprise, but smiled nonetheless, “Of course, should I address you as Remilia, just like Luna does?”
“Either that or Remi, whichever you find more appropriate,” Remi said nonchalantly, “So, should I call you Celestia then?”
Celestia nodded in approval but had something to add, “Either that or Tia, whichever you find more appealing, Remi,” she winked at the implication of pet names being used.
“Oh you do have nicknames, so which is Luna’s?” Remi asked with curiosity.
Luna was about to answer but Celestia beat her to it, “Lulu.”
“Tia!” Luna protested.
But that didn’t stop Remi’s snickering, “forgive me for laughing, I didn’t expect your nickname to be that way, but that’s kind of cute actually. So I’ll be calling you Lulu too, if you don’t mind.”
Luna softly sighed, “If that’s what you want, you can Remi. I just wanted to be the one to say it, that’s all.”
Then something popped in Remi’s mind, “now that we are talking about names, I have a question.”
“What is it about?” Celestia inquired.
Remi got into a comfortable position on her chair, “I noticed pony naming conventions are formed by two words that could be vaguely related to the mark on their flanks, I’m unsure if there are exceptions generally but that’s what I noticed.”
“Yes, that is correct. The exceptions depend on the family and the individual itself, but it’s true that ponies often obtain Cutie Marks that resemble their name,” Luna explained in some detail.
“I see… but does that mean you are also exceptions? Your names are formed by a single word plus your title as princess and I don’t think Princess is part of your names,” Remi replied as she tried to rationalize why that would be the case.
“Your train of thought is also spot on,” Celestia complimented as she developed her point, “The reason for our names to sound out of place is because as you said Princess is not part of them and also because it is not our full names. When we took over as princesses of Equestria, the need of our full names was decreasing as time passed to the point we stopped using them whatsoever, since everypony just referred to us as Princess.”
“That makes sense, but what are your full names then?” Remi questioned.
Celestia brought a hoof to her chest, “Celestia Sunshine.”
Luna mimicked her sister, “Lunaria Moonshade.”
Both of them looked at each other before flushing a bit in the cheeks and then started giggling.
“What is so funny?” Remi raised an eye-brow at the exchange.
Luna waved a reassuring hoof, “It is nothing, really. It has just been so long since we actually said our names that we almost forgot the other’s for little bit.”
“But I have to admit it is refreshing to be able to say it once again,” Celestia admitted with nostalgia.
The three of them exchanged smiles as Sakuya entered the dinner hall with breakfast ready. The rest of the time was spent with small talk and enjoying a nice meal together.
After breakfast was done the princesses decided to show Remi around the castle together with Sakuya silently following some distance away, it was still too early for day court so Celestia was free to join them.
Finishing over the hallway containing the glass windows depicting historical events of Equestria, they passed by the guards’ training area.
“This looks interesting,” she said prematurely as she started to see some issues, “well… kind of…”
“Majesties! What a pleasant surprise to have you coming around,” a male voice called and bowed, lifting his head he noticed the little vampire, “who’s our guest?”
“Captain, this is Remilia Scarlet, a very important guest from the other world we made contact with some time ago,” Luna introduced her.
“Shining Armor, captain of the Royal Guard, it’s an honor,” he introduced himself as best as he could.
Remi noticed his mark was a sparkling shield, then shrugged ‘close enough, I guess’
“Samewise captain Armor, but I’m not actually from Álfeimr,” she stated, getting a surprised look from the princesses, “the world I come from is called Gensokyo, I’am a vampire and the head of the Scarlet Devil Mansion for over five hundred years by now.”
“That said…” she paused as she gave a critical stare to the training area, “is this really the training to become guards? It seems lacking and uncoordinated to say the least.”
“Emm…” as Shining was about to reply purple teleportation happened.
“Miss Remi!” Rainbow popped out of the purple flash and immediately saluted the small vampire, “I just got told what happened, is everything ok?”
“Rainbow!” Twilight called a bit exasperated and with a disheveled mane, “Manners!”
“Sparkle, Rainbow. What a pleasant surprise,” Remi greeted in a polite manner, “as for your question Rainbow, yes. All is well, Patche is investigating to resolve this at the moment.”
“Welcome my little ponies,” Celestia said from behind, “what brings you here today?”
The messy princess of friendship just noticed her mentor, “Princess Celestia!” then Princess Luna, “Princess Luna!” then her older brother, “Shiny!”
She then grabbed Rainbow by the withers in a nervous stupor, “Oh ponyfeathers… what did we just interrupt Rainbow!?” she yelled as she vigorously shake Rainbow.
“Wait…” Remi started as she pointed at Twilight, “Is she…”
Twilight then released Rainbow, the dizzy mare falling on her back before quickly recovering. Then Twilight put her hooves in her head.
“Having…” Remi continued with a more concerned look.
Then the hyperventilation came to the friendship princess.
“A panic attack?” Remi finished, as she saw the purple pony starting to have a meltdown.
“No, no, no, no, no…” Twilight murmured as she backed away against a wall bringing a hoof to her racing chest.
“Twi/Twilight/Twiley!” everypony yelled as they tried to approach suddenly, only to be stopped by Remi and Sakuya.
Rainbow backed away as she felt something.
“What are you…” the rest tried to protest.
“Silence,” Remi ordered, as she was in the front looking at Twilight she turned her head to look at them for a moment, they flinched at the menacing glare she was giving.
‘What is this pressure?’ all of them thought at once.
Remi approached the winded alicorn princess, she then gave a nod to Sakuya.
“Captain, I suggest you tell your troops to stop their training and stay away, Princess Sparkle needs silence right now,” Sakuya coldly stated, “and some space to breath, please back away as miss Rainbow timely did,” she finished with a nod of approval to the prismatic mare.
They understood the situation and nodded, then did as they were told.
Remi sat beside Twilight and just held her other hoof in her hands as she gently caressed it with a serene expression.
Words weren’t necessary as she just needed to create a comforting ambience. Focusing her aura she tried to do just that.
‘Even though I told you that you did not need to worry about my situation… you still poked around to try and help out,’ Remi thought as she found some new respect for the pony in front of her, ‘you have changed since the first time we met, Sparkle. For that… I’m grateful.’ She ended her train of thought with a gentle smile.
Twilight’s breathing changed from erratic to more steady as time passed, changing her pained expression to a more relaxed one.
The rest could feel the change of atmosphere, it’s was soothing and peaceful. Rainbow gave a knowing smile and closed her eyes to bask into the feeling that Remi was giving out.
Finally after what seemed like an eternity, but was instead just a couple of minutes. Twilight was breathing normally, enough so she could reopen her eyes to see everypony worriedly looking at her, then her gaze fell on the one beside her.
Remi still holding Twilight’s hoof slowly opened her eyes to look at her, “welcome back,” she gave a short pause, “Twilight.” Getting a wide eyed reaction from the princess, “You should take it easy for a little moment,” she suggested while ruffling her mane.
As her job was done, Remilia stood up and started walking towards the rest of the group but she suddenly felt hooves around her body bringing her into a hug and a head resting on her shoulder. Remilia’s face sported a look of surprise for the first time.
Sakuya’s left eye twitched, the ponies on the other hoof were slack jawed at this turn of events, especially Rainbow.
“Thank you…” Twilight muttered weakly.
Smiling once again, Remi patted the distressed mare’s head, “there, there.”
That said, moments passed and the hug didn’t seem like it was ending anytime soon, Remi was starting to think it was overstaying its welcome.
Rainbow landed in front of them as Twilight continued snuggling Remi, “Emm… Twi, I don’t know if you realize what you’re doing right now,” she started.
“But could you please let go of me?” Remi finalized with hint of annoyance.
“Eh?” Twilight finally seemed to wake up from whatever trance she was in, then she noticed she was holding something at which her eyes looked slightly to the left. The realization hitting her like a sack of bricks as she started sweating bullets. She very gently placed Remi on the ground and hastily face planted the floor, “I’m sorry!”
Remi smirked with a lifted brow, “What am I going to do with you? You silly pony,” she said with a shake of her head. “It is alright, do not worry yourself with this. Just do not make a habit out of it,” Remi decided to let it pass, as she wasn’t exactly mad it just took her by surprise.
After this situation ended in a happy note, Twilight reassured everypony that she was alright. Training resumed shortly after.
Remi watched disappointingly, “Rainbow, how effective are they at defending anything?” she asked with genuine curiosity.
“Honest? Not much,” Rainbow replied in a flat tone.
“That bad, huh?”
“Hey, I take offense on that!” Shining tried and failed to defend his methods, if the deadpan stares Remi and Rainbow were giving was any clue.
“Miss Remi…” Rainbow lowered at eye level with her, “why don’t you, give them a hand?” she ended with a smirk and a wink.
“Hmm,” Remi did some quick thinking, then returned the smirk in kind, “you’re evil, Rainbow,” she said pretty much accepting Rainbow’s idea which filled the prismatic mare with excitement.
“Captain Armor,” she called for the still offended stallion, getting his attention, “I shall take over training right now, if you don’t mind.” She said matter-of-factly.
“Wait, I don’t intent to be rude, but do you know about military training? I wouldn’t want our guest to be hurt by playing over here,” he replied in what he thought was the nicest way possible.
“Oh ho~ this one has some spunk into him,” Remi was starting to get some devious ideas.
“Please don’t hurt him…” Twilight pleaded from behind them.
“Wha…” Shining was about to say something but Rainbow interrupted him.
“Are you kidding me, dude? I know you felt it too, Miss Remi’s overwhelming aura. But you still want to defy her decisions?” Rainbow argued, knowing pretty well what Remilia was capable of.
“I did notice, that’s why I can’t have the one who helped my little sister getting hurt here, if she doesn’t have combat experience,” he shot back in a reasonable way.
Remilia floated in front of Shining Armor with a mischievous smile, “why don’t you spar with me then, captain?” her smile growing bigger showing more of her fangs, “that way you can make sure I don’t hurt myself.”
After some thought Shining nodded, “Alright, don’t worry I’ll go easy on you.”
Remilia’s eyes slightly sharpened before quickly changing her expression to one of smiley innocence, “thank you, I appreciate it.”
Everyone surrounded the arena that was going to be used for this spar session, some with anticipation, some with worry.
As Remi made her way towards her side of the arena, “I’m going to have some fun~” she sang as she passed in front of Rainbow, Twilight and the princesses.
“Uh-oh,” both ponies that knew her had a bad feeling, this got a confused reaction from the princesses.
Before anything started, two airborne mares that were heading towards the castle just noticed the commotion, “that looks interesting, let’s check it out!”
